Abstract

A Babesia microti-like rodent parasite was isolated from the tick, Ixodes persulcatus, collected from the northern forest area of Heilongjiang province, China. The collected I. persulcatus were allowed to feed on specific pathogen-free SCID mice and red blood cells from the mice were used to isolate Babesia spp. with the microareophilous stationary-phase culture technique. Paired and tetrad forms of merozoites were observed by light microscope in red blood cells of SCID mice. In vitro growth of the parasites was also achieved in mice erythrocytes, which indicated the presence of Babesia spp. in I. persulactus. To further identify the Babesia species, polymerase chain reaction screening and subsequent sequencing of nuclear small subunit ribosomal RNA (nss-rRNA) was employed. The results indicate that the observed parasites might be an isolate strain responsible for human babesiosis -B. microti - which has 99.3% identity with that of B. microti isolate RcM5201 (AB112050) from Mishan in Heilongjiang and Kobe isolates from Japan. In addition, the infection rate of B. microti in I. persulcatus ticks in the region was 3.6-4.0% in adult females and no infection in males. Though the infection rate is low, the high attack frequency of t...Continue Reading
